easily reacts with phosphoruspentachloride in CCl4 yielding the relatively stable (1,3,3-trichloro-2,2,4,4-tetramethylcyclobutyl)sulfenyl chloride (3c). The reactions of 3c with benzylsulfane (4) and thiocamphor (5) occur with elimination of HCl leading to the unsymmetrical disulfanes 6 and 9. In the case of the sulfenates 10 and 12, which are formed as intermediates in the reactions of 3c with propargyl
